Installed in a high density Perle Media Converter Chassis, Perle's feature rich SFP to SFP protocol and rate-transparent media converters enable network administrators to incorporate multiple fiber types and wavelengths in, or between, networks through fiber to fiber mode conversion. Using this technology will result in significant cost savings when compared to replacing an optical blade on network equipment. Easily extend a network to remote locations by converting:

SFP to SFP Conversion

The CM-4GPT-DSFP Managed Fiber Mode Converter Module comes with two empty SFP slots. This allows for flexible network configurations using SFP fiber transceivers supplied by Perle, Cisco or other manufacturers of MSA compliant SFPs. Adapting to different fiber types, distances and wavelengths is made simple by mixing and matching SFP’s as needed for maximum flexibility across a variety of topologies and network architectures. The hot-swappable nature of SFPs allow for easy configuration and future upgrades as network demands evolve by simply upgrading a single SFP instead of replacing the entire fiber mode converter.

Convert different wavelengths ( WDM Transponders )

SFP transceivers also enable the C-4GPT-DSFP Fiber Mode Converter Module to operate as a Wave Division Multiplexing (WDM) transponder. Also referred to as Bi-Directional ( BiDi ) or Simplex, WDM Transponders help network administrators take advantage of the cost savings in both material and labour associated with Single Strand Fiber. WDM uses separate transmit and receive frequencies to communicate on a single fiber strand. WDM technology relies on the fact that optical fibers can carry many wavelengths of light simultaneously without interaction between each wavelength. Thus, a single fiber can carry many separate wavelength signals or channels simultaneously. WDM systems are divided into different wavelength patterns, conventional/coarse (CWDM) and dense (DWDM).

CM-4GPT-DSFP Managed Fiber Mode Converter Module Features

Network Administrators can “see-everything” with Perle’s advanced features such as Smart Link Pass-Through and Fiber Fault Alert. This allows for more efficient troubleshooting and less on-site maintenance. These cost and time saving features, along with a lifetime warranty and free worldwide technical support, make the CM-4GPT-DSFP Fiber Mode Converter Module the smart choice for IT professionals.

Smart Link Pass-Through when enabled ensures that the link state on a fiber connection is directly reflected through the media converter to the other connection. If link is lost on one of the connections, then the other link will be brought down by the media converter. This feature applies when both SFP slots are occupied.

If set in Standard Mode, the link is kept active. The unit will transmit a 25Mhz keep-alive signal to artificially keep the link up.

Fiber Fault Alert

If the media converter module detects a loss of fiber, it will immediately notify the fiber link partner that an error condition exists.

Indicators

Power

This green LED is turned on when power is applied to the media converter. This LED is off when there is no power supplied.

A Blinking LED will indicate that a hardware error has been detected.

LK1

LED is ON when a signal is detected on LK1. LED is OFF when there is no signal.

LK2

LED is ON when a signal is detected on LK2. LED is OFF when there is no signal.

Switches

Link Mode

Smart Link Pass-Through when enabled ( Default ) ensures that the link state on a fiber connection is directly reflected through the media converter to the other connection. If link is lost on one of the connections, then the other link will be brought down by the media converter. This feature applies when both SFP slots are occupied.

If set in Standard Mode, the link is kept active. The unit will transmit a 25Mhz keep-alive signal to artificially keep the link up.

Fiber Fault Alert

If the media converter module detects a loss of fiber, it will immediately notify the fiber link partner that an error condition exists.

Disabled ( Default ). The Media Converter will not monitor for fiber fault.

Multi-speed SFP

When enabled, identifies that the SFPs inserted are MSA complaint SFPs that have a multi-rate capability SFF-8074 and SFF-8472.

When disable ( Default ), no action is performed in this context.

Rate Select

This enables rate selection when using dual-rate capable SFPs. If the “Multi-Speed SFP” select switch is in the “Disabled” position, this switch is ignored.

High Speed - UP ( default )

Low Speed – DOWN

2 x SFP Slots

SFPs

SFP line rates up to 4.25Gbps are supported. The SFPs occupying each slot in the media converter however must be operating at the same speed.

Interconnect Multiple Fiber Types and Wavelengths

Managed SFP to SFP protocol-transparent fiber mode converters enable network administrators to incorporate multiple fiber types and wavelengths within or between networks. See below some examples. The fiber link on the managed standalone unit can provide vital information and status to network management tools such as SNMP.
